T0 all 'w 7mm t may concern.-

Be it known' that l, OLE HKoNsnN, a subject of the King of Norway,residing at Slrudenes, Norway, have invented a new and useful Foghorn-tor Motor Crafts, of which the following is a specification.,

rIhis inventionv relates to a fog-horn for motor crafts.'lhe'es'sentially new feature consists in that the compressed airrequired 'for the action of the horn, is taken 'from the crank chamberof the motor. With the two cycle motors, generally used in motor crafts,the crank chamber, it is well known, is incased and acts as an aircompressor for the motor.

A. construction of the invention is illustrated in the accompanyingdrawings in which f Fig. 1 is a vertical section along the line A-B-C-Din Fig. 2.

Fig. 2 is a horizontal section along the line EF in Fig. 1. i

Fig. 3 is a vertical 'cross section along the line G-H in Fig. 1.

The whole apparatus is mounted in a boX 1 which is divided by ahorizontal board 2 into two compartments. The board 2 forms the upperside of a bellows 3, the bottom 4 of which is pressed upwards by twospiral springs 5.

In a hole in the board there is placed a valve-casing 6, the verticalbore 7 of which is at its under end closed by a valve 8, that is pressedupwards by a spiral spring. Above the bore 7 there is placed anothervalve 9, which is by a stem 10 anda traverse 11 connected with twovertically movable rods-12.` These rods are placed one on each side ofthe bellows and are slidable in a traverse 18 attached to the' underside oi' the bellows. The rods are guided in. holes in the board 2 andare together with the' valve 9 pressed upwards by spiral springs 14.

The valve-easing 6 is connected with the y crank chamber ofthe motor bya pipe 15, and the compressed air enters the bellows through the valve 8and the holes 16 in the valve casing 6. On iilling the bellows withcompressed air, its bottom and with it the traverse 13 is presseddownwards. When the bellows has been nearly filled, -the traverse pushesagainst thegnuts 17-on the rods 12. Hereby the rods and with them alsothe valve 9 are moved downwards. At last the valve shuts in this way thebore 7, and the entrance or' compressed air ythereby ceasesautomatically. n

Onthe board 2 there is also placed another valve-casing 1S, which is inconnection with the bellows by the air-holes 19 and 20, while it is onthe other side connected with the horn 21. ln the valve-casing therek isa valve 22 which is pressed upwards by ka spiral spring and usuallyshuts ofi' the flow of air 4to the horn. The valve is connected with. astem 23 and can be moved downwards by a lever 25, pivoted at 24 and atits free end connected with a cord 26.k

By pulling thek cord 26 the valve 22 is f opened, whereby the bellowswill, by the action of the springs 5, blow air through rthe horn whichis in this way brought into ac'- tion'.

As the bellows is now being pressed together, the springs 14 will liftthe rods 12 and therewith the valve 9; hereby there isA letautomatically new air into the bellows, until the latter has beenrefilled.

The construction of the apparatus may be varied in many ways withoutdeparting from the principle of the invention. For example theva-lve-casings need not be placed directly on the bellows, but can beconnected with the latter by pipings. Instead' of springs 5 forcompressing the bellows other devices may be used, for instance,weights. Instead of a bellows any other pressure ac'- cuniulator mayalso be used.

What l claim and desire to secure by LettersV Patent of the UnitedStates is 1. A. signaling device comprising an 'air reservoir beingconnected to a source of fcompressed air, means interposed'between saidsource and said reservoir to control the pas-V sage of air to thelatter, a horn connected to said reservoir and adapted to be operated bycompressed air, means interposed between the reservoir-tand said hornfor con'- trolling the ypassage-of air from said reservoir to -saidhorn,`and means cooperating with said 'reservoirto reduce its capacity,

wherebyfuniform air pressure ymay be main tained in the reservoir as theair volume decreases.

`2. A signa-1mg device comprising an rair by compressed air, meansnormally preventing passage of air from said reservoir to said horn,said means being operable to permit passage of air from said reservoirto said horn, and means cooperating with said reservoir to reduce itscapacity, whereby uniform air pressure may be maintained in thereservoir as the air volume decreases.

3. A signaling device comprising a flexible air reservoir, saidreservoir being connected to al source of compressed air which normallyholds it expanded, means interposed between said source and saidreservoir to control the passage of air to the latter, a horn connectedto said reservoir and adapted to be operated by compressed air, a valveinterposed between said reservoir and said horn and normally closed toprevent passage of air from said reservoir to said horn, means foropening said valve to permit passage of air `from said reservoir to saidhornj and means whereby the reservoir is collapsed to discharge the aircontained therein through the horn when said valve is opened.
